Abstract:

The 1-hour average mass concentration of CO, NO2, SO2, O3, PM2.5 and PM10 from November 2013 to the first half of April 2014 obtained from 35 air automatic monitoring sites in Beijing was used to analyze temporal and spatial distribution of atmospheric pollutants. The results show that the average concentration for CO, NO2, SO2, O3, PM2.5 and PM10 in heating season was 2.62 mg/m3, 64.05 μg/m3, 50.52 μg/m3, 26.39 μg/m3, 118.61 μg/m3 and 126.05 μg/m3 respectively. The concentration of NO2 changes slightly, and the highest concentrations of SO2 and particulate matter are in February, CO shows a steady downward trend, while O3 is gradually increased. NO2, PM2.5 and PM10 concentration diurnal variation show a bimodal. With fine particulate pollution levels increased the proportion of PM2.5 in PM10 and the concentrations of NO2, CO, SO2 gradually rises, the O3 change trend is opposite. The concentration of O3 is the highest in comparative and regional stations respectively, while that of other pollutants is the highest in traffic pollution monitoring stations. The distribution of atmospheric pollutants mass concentration in heating season in Beijing is derived by the Original Kriging interpolation method, and it shows from the figure that the concentrations of PM10, PM2.5, CO, NO2, SO2 gradually increases from the northern mountain area to the southern part of Beijing. O3 concentration in the urban area is significantly inferior to other regions. © 2016, Editorial Department of Journal of Beijing University of Technology. All right reserved.
